Just updating this thread to announce the release of a thermostatic option for the Mishimoto 370Z direct fit oil cooler kit. Not only this but the kit can now be purchased with a black or silver cooler. So if you are going for that stealth look, this is the kit for you.

Nissan 370Z Oil Cooler Kit & Infiniti G37 Oil Cooler Kit

Feel free to send any questions my way!

Thanks

I'm guessing some drilling will still be required to mount the core, similar to other kits? I think one hole is needed on the vertical piece in front to bolt the core, and another on the passenger side to route the lines.

Also - WRT to the thermostatic switch, would love thoughts on having the temperature set at 180 vs 200 (which I think is unique to your kit). Since the stock car runs at about 200 degrees, my thought is to have the switch set to 200 as well. Any advantage to setting the switch cooler?

Does the thermostatic plate come with the 185 degree thermostat? Maybe I missed it on the website

Drilling is not necessary when installing our kit. For cooler mounting we use existing holes on the radiator support and supply threaded clips and mounting hardware. The lines are routed around the radiator along with your power steering cooler lines.

Our engineers found that engine oil begins to flow efficiently around 180 degrees. Using our 185 degree thermostat ensures that the oil will not be cooled until this temperature was reached. This allows for normal warmup and extremely efficient cooling after that temperature is reached.

The 370Z has numerous cooling issues and limp mode is pretty easy to activate even while street driving. We were able to set off limp mode (280F) in our test vehicle rather quickly. With the Mishimoto oil cooler installed we were unable to do so and had fantastic cooling results.

Let me know if you have any other questions!

Thanks

This is correct! :tup:

I know you have faith in the 19 row core and I'm sure it does keep the Z out of limp mode. However, I think a 25 row option might get more attention. I'd like to keep my oil temps below 250F pushing the car all out. I don't have much confidence that a 19 row can do that in 90-105 degree summer heat. In pictures and in spec sheets, it appears to have the same width, depth and fin density as other 19 row coolers that aren't cutting it for track use.

Is there any possibility of a larger core option in the future?

I completely agree with you! We do have faith that our 19 row will handle oil temperature problems and we would like to offer a larger core for those of you who would prefer even further temperature protection.

We are working on a 25 row cooler that will hit shelves this summer and soon after we will be investigating its fitment into our direct fit oil cooler line. We will have to make modifications to the current 370Z kit to accommodate the larger core but we will certainly be doing test fitting. I am unable to provide an exact or estimated date but I will do my best to keep the community up to date!

Thanks for the feedback Mandingo. :tup:

You guys should really do your research in Humid extremely hot states. IE Texas. In El Paso I would not recommend nothing below a 25 row. Z1 has a good cooler. Simple Install.

John, I am sure you meant to say you are working on a 25 or 34 row cooler.

After it's release this summer, do you expect the price to come down on the 19 row cooler? I do not plan to ever track my Z, but I am very interested in protecting the engine/oil especially during the Summer Months.

I would love to get a Mishimoto 19 row Oil Cooler but the cost is very high at this time. There are other, less expensive, alternatives for 19 row coolers out there.

Thanks for the response John! I'm assuming you meant to type '25 row cooler' in the second paragraph. That or a 34 row will surely help battle the heat

Thanks! We will certainly do our best to get the most accurate data when testing. If testing occurs this summer we should be able to select a date when high temperatures are expected.

My mistake guys! Thanks for pointing that out. I did intend to type 25 row. I am not 100% positive on how pricing will be effected with the release of a new kit. It is still a bit out on the schedule so once we get a bit closer I should be able to provide more details.
